There are numerous treatments for cancer. These include surgery, chemotherapy, radiotherapy, hormone therapy, and stem cell and bone marrow transplants.

There are numerous treatments for cancer. The aim of any treatment is to remove cancerous cells to try to ensure the cancer doesn't return. This can be challenging because even if just one cancerous cell remains after treatment, it has the potential to create a new tumour.

The main techniques used to treat cancer are listed below.

Surgery

Surgery is a common treatment option. However, the type of surgery a person has and when they have it depends on which cancer it is and what stage it's at.

Surgery removes the tumour and some normal tissue surrounding it. The removed tissue is sent to a laboratory for analysis and the results help doctors to decide whether further treatment, such as radiotherapy or chemotherapy, is needed.

Chemotherapy

During chemotherapy, powerful medicine is used to kill cancerous cells. It can be given either as a tablet or directly into a vein, using an injection or infusion.

There are more than 100 different types of chemotherapy medication (and new ones are being developed all the time) that can be used to treat hundreds of different types of cancer.

Radiotherapy

Radiotherapy, also known as radiation treatment, can also be used to treat many forms of cancer. It can be given outside the body by using X-rays, or inside the body using a liquid that's either swallowed or injected, or by putting radioactive material in or close to the tumour. About half of all people with cancer have radiotherapy as part of their treatment plan.

Hormone therapy

Hormone therapy works by lowering the levels of hormones in your body or by stopping their effects. Prostate cancer in particular needs testosterone to grow, and some breast cancers are stimulated by oestrogen or progesterone.

Biological therapy

Biological therapies are treatments that affect the processes that occur in cells. They can:

stop cancerous cells dividing and growing

seek out and destroy cancerous cells

encourage the immune system to attack cancerous cells (immunotherapy)

Interferon and interleukin are two substances that are sometimes used during immunotherapy to boost the immune system and help treat certain types of cancer, such as kidney cancer.

Stem cell and bone marrow transplants

Complementary and alternative therapies

Complementary therapies can be used alongside conventional cancer treatments. They can sometimes improve a person’s quality of life by helping them cope better with their cancer symptoms or the side effects of their cancer treatment.
